Netbeans 7 and SS

Hej,
I'm a webintegration/Multimedia design student living in Denmark. After looking briefly to CodeIgniter and fighting with Drupal for the last 4 months I have found Silverstripe, when looking for a CMS that would make my life easier and help me to build a website for the kayak club I'm member of. What made me interested in SS is actually the Booking Calendar module (which I haven't yet tried but looks very promising); I am also very interested in MVC programming and look forward to learning more of it.

Now my question, which I know has been posted elsewhere, but I post it here again because I haven't found a satisfying answer: I work mainly with Netbeans (updated yesterday to NB 7) and I would like to have sintax-highlighting and code completion for .ss files. I have already added .ss files to Netbeans configuration but this is not enough for having these two features running.

Well, I know there is people here working with Netbeans. How have you configured your IDE? Help is appreciated.

Also if you happen to enjoy Aptana 3 (which I also like) tips regarding this are also appreciated.

But does this configuration resolve your problems with autocompletion and sintax highlighting? It doesn't in my case and I had that very same configuration regarding .ss files (I had found how to in the Netbeans forums).

When I open an .ss file in Netbeans 7 I got HTML highlighted but SS special tags are not highlighted and they are treated as errors (see screenshot ss_errorsNB7)

I'm using netbeans 6.9 and I don't remember I did anything except that option. For me the SS special tags are showing in white and and normal not errors.. try double clicking on that error and see if it gives an option to disable errors for that special tag..
